▎Frequently Asked Questions
Q: How does the XHLJ504L integrate into construction site safety protocols?
The XHLJ504L should be used as part of a comprehensive pre-excavation safety procedure: (1) Obtain utility plans from relevant authorities, (2) Use the XHLJ504L to physically verify cable positions and depths on site, (3) Mark detected cable routes with appropriate color-coded spray paint, (4) Conduct trial pits at critical locations to visually confirm findings. This layered approach ensures compliance with construction safety regulations.
Q: What is the training requirement for construction crew operators?
Most operators achieve basic proficiency within one day of hands-on training, covering: instrument setup, signal application method selection, frequency choice, path tracing and marking, and depth measurement with verification. For construction companies, formal on-site training programs are available that include practical exercises on representative job sites and competency assessment.
Q: Can the instrument's findings be used for as-built documentation?
Yes. Cable path measurements, depth readings, and marked utility positions documented during pre-construction surveys serve as valuable as-built records. When combined with GPS coordinates and photographs, this data can be incorporated into project documentation, GIS databases, and handover packages for future reference by asset owners and maintenance teams.
Q: How does weather affect detection accuracy on construction sites?
Heavy rain can improve soil conductivity, potentially enhancing signal propagation for deeper cables. However, standing water on site can create surface current paths that produce false readings. Extreme cold may reduce battery performance. The XHLJ504L operates reliably from -15°C to +55°C, covering most construction season conditions. In wet conditions, ensure all connectors and battery compartments are properly sealed.
Q: What warranty and support is provided?
12-month standard warranty against manufacturing defects with lifetime technical support. CE and ISO certified. Complete kit includes receiver, transmitter, connection cables, coupling clamp, ground rod, rechargeable batteries, chargers, user manual, and a rugged transport case suitable for construction site environments. On-site training programs tailored to construction survey applications are available.
